Clynnog Fawr, often just referred to as Clynnog, has long been a resting point for pilgrims making their way to Ynys Enlli/Bardsey Island at the tip of the peninsula. These pilgrims would have taken refuge in the village's large church, dedicated to St. Beuno - and many still make the journey along the peninsula today, for many as part of a walking holiday in the area.

Clynnog is nestled between the hills of Bwlch Mawr and Caernarfon Bay and currently lies along the A499 between Pwllheli and Caernarfon, however road improvements are underway which will see Clynnog bypassed.
